Abstract:
A maintenance and hygiene method and apparatus (50) for a motor vehicle air conditioning system (30) with a cooling circuit (20'). The apparatus comprises a regeneration device (56) and a hygiene device (57) that are integrated in a single body (51) which includes, furthermore, a program means (55) that contemporaneously actuates and controls the regeneration device (56) and the hygiene device (57). The maintenance and hygiene program that is resident in the memory of the microprocessor (55) is then started by an operator. In particular, the hygiene step is carried out contemporaneously with the step of recovering the cooling fluid and with the engine on, and is prolonged up to a lubricating fluid discharging step/establishing vacuum condition step. This way, an important advantage is achieved in terms of operating time and cost reduction, since the operations of regeneration and of hygiene are simultaneously carried out; moreover, the operating space is reduced in comparison with the space needed for the two prior art distinct devices.
Abstract:
A mist-generating device that can be connected to a vehicle's Low Direct Current Voltage (LDCV) power supply is disclosed. The device can be used to treat mold, bacteria and clean or remove odors on exposed and hard-to-reach surfaces of the interior of a car. The device can include a unique filling system that can be used to prevent foreign materials from entering into the unit, including fluids or substances that would deteriorate the performance of the unit or the components of the device itself. The inside of the device can include an internal anti-foam and anti-splash structure designed to keep electronic components dry and reduce the foaming and turbulence of the fluid being misted. Further, the inside of the device in one embodiment is split into three adjacent areas, which govern efficient flow of air and atomized chemicals through the device.

Abstract:
The present invention relates to an air dehumidification and heating system (1), which supplies dry and hot air free-of-bacteria into the vehicle cabin, and basically comprises at least one atomizer (2) which enables to pulverize and atomize water, at least one intake air line (3) which enables the outer environment air (H) to be mixed with the pulverized water coming from the atomizer (2) and which enables to transfer this mixture, at least one liquid desiccant container (4) in which the liquid-air mixture coming from the intake air line (3) is atomized to the solution therein via sprinkling method and supplies hot, dry and clean air, at least one solution pump (41) which is connected to the liquid desiccant container (4) and enables the solution in the liquid desiccant container (4) to be mixed, at least one ejector (42) which is located at the end of the solution pump (41), at least one clean air line (5) which is connected to the liquid desiccant container (4) and enables the solution in the liquid desiccant container (4) to be mixed, at least one HVAC module (6) into which the hot, dry and clean air coming from the clean air line (5) enters, at least one fan (61) which enables the hot, dry and clean air to enter into the HVAC module (6), at least one serpentine (62) which enables to increase the heat of the hot, dry and clean air within the HVAC module (6), at least one evaporator (7) in which the solution whose concentration has decreased inside the liquid desiccant container (4) is evaporated, at least one vapor heater connection (8) which enables the hot water vapor leaving the evaporator (7) to be delivered to the serpentine (62) located in the HVAC module (6), at least one waste hot water pipe (9) which enables the waste hot water vapor in the serpentine (62) to be delivered to the atomizer (2), at least one water charging component (10) to which a part of the water in the waste hot water pipe (9) is delivered.
Abstract:
Disclosed therein is a drying device, which can prevent generation of bad smell from condensate and foreign matters remaining on an evaporator and an evaporator case when the air-conditioner, which is used seasonlessly, is re-operated after being used. More particularly, the present invention relates to a drying device of an air-conditioner for automobiles, which includes a duct opening/closing door and a discharge opening/closing door, so that high-temperature and dried air, which is generated in such a way that the outdoor air introduced from an air blower is converted by high-temperature heat (about 9O°C or more) of engine refrigerant circulating inside a heater core, is not introduced to the inside of the automobile by intercept of the duct opening/closing door but flows backwardly and passes through an evaporator to dry residual condensate remaining in the evaporator, and high-temperature and high-humidity air generated by the above is compulsively discharged to the outside through the discharge opening/closing door, thereby providing just fresh cooled air to the inside of the automobile when the air-conditioner is re-operated.
Abstract:
A self tapping spray nozzle (10) for use in a vehicle ventilation system is preferably made of stainless steel. The spray nozzle has a neck (12) with an internal channel (34) and threads (17) cut into its outside surface. A wedge at a thirty degree angle, having sharpened edges is at the top of the neck. At least one port (14, 15) extends from the channel to the outside surface of the neck. A collar (13) with a plurality of sides (19) encompasses the circumference of the neck at its bottom. One side of the collar is aligned with the port to help align the port in a desired direction.
Abstract:
A detergent for automotive air conditioners which comprises water as the base, a surfactant, and a liquefied gas as an aerosol propellant and has been packaged in a container fitted with a jet nozzle. The detergent contains a volatile alkaline substance. It is alkaline before volatilization of the alkaline substance and becomes neutral upon volatilization thereof. When the detergent is ejected through a detergent injection tube attached to the jet nozzle, it comes into a mousse-like state and then becomes liquid within a period of from one to ten minutes thereafter.
